Platinum efficiency and the ability to deliver its full power continuously at up to 50 °C are some of the unit's key features. It also has all the necessary protection features, and its top-notch cooling fan uses a Fluid Dynamic Bearing (FDB), which is the best bearing type around. As with most modern PSU, this one is also Haswell ready, and most of its cables are modular. be quiet! could have easily made all cables modular, but as has already been stated, keeps insisting on keeping the main ATX cable native. Strangely enough, there is no passive mode, a feature most high-end offerings in this category sport, and the PSU is large since it is more than 19 cm deep. At 5 years, its warranty is pretty long, and its price looks stiff, but this product screams of quality, which partially justifies the price.

At 150 W maximum power output, the minor rails are very strong, and there are four +12V rails that can be combined into one for almost 1 kW. The 5VSB rail is strong enough, but a few more watts would have been nice.

The P11-1000 comes with a ton of cables and connectors, enough to easily make use of or even push a 1 kW PSU beyond its limits with several power hungry components. With eight PCIe connectors, it can power up to four high-end VGAs, but its maximum power output will set the bar here since multiple Nvidia GPUs at stock speeds can consume more than 800W. Power consumption would even be higher with AMD's offerings as their cards usually register a lower performance-per-watt ratio. Six PCIe connectors with a seventh for the mainboard would have been enough. Nine PCIe connectors might look great on paper, but are clearly too many for 1 kW, especially when combined with two EPS connectors.
There are enough SATA and 4-pin Molex connectors, and the P11-1000 can also power and thermally control four additional fans, which may make a fan controller for case fans obsolete. All PCIe and EPS connectors also use thicker 16AWG gauges, and the same applies to the +12V wires of the 24-pin ATX connector. All other wires are 18AWG, which is the norm.

Power distribution is optimal since EPS and PCIe connectors are kept separate. The photo below is of the modular board's rear panel, which shows the EPS and PCIe numbers we listed in the table above.
